'SWAGE ATTACHMENT-FOR ANVILS. v

Patented Apr. 15, 1919. Application filed July 11,1918. Serial No. 244,423. 1 r

To all whom it may concern:

. Beitknown that I, ABRAHAM L. AMos, a citizen of the United States, residing at South Bend, in the county of Saint Joseph, State of Indiana, have invented a new and useful Swage Attachment for I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a swage attachment for anvils, and has for its object to provide a device of this character which embodies novel features of construction whereby a blacksmith can use the swage without the need of a helper, thereby simplifying and reducing the cost of swaging and shaping articles when forging.

Further objects of the invention are to provide a device of this character which can be readily applied as an attachment to any ordinary anvil, which can be quickly adjusted for use in connection with different sizes of work, and which can be used in an effective manner by one person. I

With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention,

reference is to be had to the following de-' scription and accompanying drawings, in which Figure 1 is a side elevation of a swage attachment for anvils constructed in accordance with the invention.

Fig. 2 is a longitudinal vertical sectional view through the same with portions of the supporting frame broken away.

Fig. 3 is a side elevation of an anvil with the attachment applied thereto, one end of the anvil being broken away and shown in section.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters. 1

Referring to the drawings, the reference character A designates an upright frame which has a substantially U-shaped formation, being formed with superposed upper and lower horizontally extending arms 1 and 2, respectively. The lower arm 2 ter- Anvils; and

minates in a rectangular base block 3 which tional form of anvil being indicated by B.

in Fig. 3. A stem 6 projects from theouter face of the base block 3, said stem being arranged in substantial alinement with the lower arm 2 of the frame A, and having a swage block 7 mounted thereon. The outer end of the stem 6v is threaded and receives a nut 8 which serves to hold the swage block in proper position upon; the stem. The swage block 8 is rectangular in shape and is provided in the four outer sides thereof with transverse grooves 9, all of the said grooves being of different sizes, and any selected one of the grooves being adapted to be rotated upwardly and brought into operative position for swaging or shaping, according to the size of the material which is being forged. The lower face of the lower swage block 7 rests squarely on. thetop of the anvil B so as to obtain a firm bearingthereon, and in order to rotate the swage block to bring a different one of. he grooved faces 9- up: wardly into operative position it is necessary to partially lift the tang 4' from the opening 5 in the anvil in order to provide a clearance space for the corners of the block as it is turned.

The upper arm 1 of the frame A terminates in a vertically disposed guide sleeve 10 which slidably receives a plunger 11, the lower end of the plunger terminating in a socket 12 which has an upper swage block 13 fitted therein. The upper swage block is an exact counterpart of the lower swage block, and is interchangeable therewith, being provided with grooved faces 14 which correspond to the grooved faces 9 of the lower block. Suitable means such as a set screw 15 is provided for locking the upper swage block 13 in position within the socket 12, and the swage block can be fitted in the socket with one of the grooved faces 14 facing downwardly in an opposed relation to the upper face of the lower swage block 7. A coil spring 16 surrounds the plunger 11, being connected at the upper end thereof to the guide sleeve 10 as indicated at 17, and being connected at the lower end thereof to the socket 12, as indicated at 18. The upper end of the plunger 11 extends upwardly above the 7 guide sleeve 10 and is adapted to be struck with a hammer C, such as is indicated by dotted lines on Fig. 3. The upper swage block 13 will thus be forcibly driven downward against a piece of work which has been interposed between the two swage blocks, and the work will thus be swaged or shaped in the usual manner. However, the upper swage member is supported by the frame so that it is not necessary to employ a helper to strike: the upper swage member or hold it in position; A blacksmith is thus enabled to" perform the work without the use of a helper and by adjusting the position of the upper and lower swage blocks different swage faces can be brought into operative position for shapingdifier'ent sizes of work. 7

Having thus described the invention, what I-claim as new and desire to secure by Letters Patent, is:

1. A swage attachment for anvils includ ing an upright frame formed with upper and lower superposed lateral arms, "a. base block at the end of the lower arm, a positioning tang projecting downwardly from the base block and adapted to enter the opening of the anvil, a horizontal stem projecting from the end of the base block, apo-l'ygonal swage block rotatably mounted upon the stem and formed with aseries of grooved faces any selected one of which can be'rotated upwardly into operative position, the lowermost face of the swag'e block resting upon and engaging swage block in an adjusted position while the device is in use,a vertical guide sleeve carried up er arm, a spring retract- Copies or this patent may be obtained for five cents the anvil to hold the r ed plunger slidable through the guide sleeve, and an upper swage block carried by the plunger for cooperation with th first mentioned swag block.

2. A swage attachment for anvils including an upright frame formed with upper and lower superposed lateral arms, base block at the end of the lower arm, a positioning tang projecting downwardly from the base block and adapted to enter the open ing of the-anvil, a horizontal stem projecting from the end of the base block, 'a polygonal swage block ,otatably mounted upon the stem and formed with a series of grooved faces any selected one of which can be ro tated upwardly into operative position; the lowermost face of the swage block resting upon the anvil'to prevent rotation of the swage' block when the device is in use,

a vertical guide sleeve carried by the upper arm, a spring retracted plunger slidable' through the; guide sleeve and having a socket at the lower end thereof, an upper swage the socket and groove faces of be brought'into operative position ing means for clamping th formed with; a series of which any selected one can and locke upper swage block in an adjusted position within the socket.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
